Incidental findings of renal masses are increasing. However, a substantial portion of surgically treated renal masses turn out to be benign on histopathological examination. Thus, there is a clear need for improved pre-surgical assessment to minimize unnecessary invasive procedures. The challenge intensifies when distinguishing between renal cell carcinoma (RCC) and angiomyolipoma (AML) in renal lesions smaller than 4 cm with minimal adipose tissue. In such cases, contrast-enhanced ultrasound (CEUS) has emerged as a valuable diagnostic tool, by utilizing both qualitative and quantitative parameters. Quantitative measures offer objectivity, reliability, and reproducibility compared to qualitative parameters, enabling the characterization of RCC subtypes and differentiation from AML. Qualitative features as enhancement pattern, degree, and peak were less helpful in distinguishing triphasic minimal fat AML (TAML) from epithelioid AML (EAML), with the pseudocapsule sign potentially being the only distinguishing qualitative feature. The pseudocapsule sign was more frequently observed in ccRCCs (38.0%) than in AMLs (15.6%). Moreover, it was detected in 40.0% of EAMLs and 34.5% of ccRCCs but not in TAMLs due to similar growth patterns between EAMLs and low-grade ccRCCs. Quantitative measures such as the time-to-peak (TTP) ratio can further enhance diagnostic accuracy and also TOC ratio should be considered, as it was higher in clear cell RCCs (ccRCCs) and in EAMLs compared to TAMLs, indicating behavior similar to ccRCCs. However, CEUS remains an operator-dependent exam., (© 2024. The Author(s).)

Inferior vena cava leiomyosarcoma is a rare malignant mesenchymal tumor that originates from the smooth muscle cells of the venous media and is more frequent in females in the V-VI decade of life. Due to scarce and specific symptoms, diagnosis is not simple, and often metastases to the liver, lungs, and/or lymph nodes are already present. A 44-year-old male patient arrives at our institution presenting diffuse abdominal pain and a sense of weight associated with lumbar pain. He showed nothing relevant except for a moderate consumption of alcohol. Ultrasound examination of the abdomen revealed liver enlargement with hyperechoic nodularity and clear margins. Furthermore, the presence of a voluminous solid nodular formation was found, with an inhomogeneous echostructure and moderate vascularization on Doppler. Inferior vena cava leiomyosarcoma is a rare malignancy. The diagnosis is usually established after surgery, however, recurrences are common and the role of chemoradiation therapy remains to be defined. The only potential treatment is surgical resection with possible vessel reconstruction and en bloc removal of adjacent structures with 5 and 10-year survival rates of 49% and 29%, respectively., (© 2023 The Authors.

Liposarcoma of the spermatic cord is a malignant neoformation so rare that less than 200 cases are reported in the world. It is a tumor that originates from adipose tissue and when it is found in the spermatic cord it can deceptively simulate an inguinal hernia and not be easily identified. The present work describes the case of a 37-year-old man with liposarcoma of the spermatic cord who arrives at our institution with painless swelling of the left testicle. Physical examination revealed a painless swelling in the scrotal sac. The scrotal ultrasound examination revealed a mass, measuring 8 cm (cranio-caudal) × 5.4 cm (latero-lateral) × 8 cm (antero-posterior) and characterized later with a basal CT examination of the abdomen. The patient was subsequently surgically treated with excision of the tumor, plus hernial plastic with plug and mesh. Histological examination revealed a mature adipocyte neoplasm whose morphological and molecular characteristics (amplification of the MDM2 gene) are consistent with the diagnosis of dediferrentiated liposarcoma variety CO-MINGLED, G2 (sec. FNCLCC) . The patient is currently under cancer surveillance with no signs of loco-regional recurrence. Spermatic cord liposarcoma is an extremely rare malignancy. It's not easy to identify as it can simulate an inguinal hernia, hydrocele, lipoma, funicular cyst, or testicular tumor. Diagnosis is usually established postsurgery, however, relapses are common and the role of chemo-radiotherapy remains to be defined., (© 2023 The Authors.)

Purpose: To study the prognostic value for overall survival of baseline assessment of functional status, comorbidity, and quality of life (QoL) in elderly patients with advanced non-small-cell lung cancer treated with chemotherapy., Patients and Methods: Data from 566 patients enrolled onto the phase III randomized Multicenter Italian Lung Cancer in the Elderly Study (MILES) study were analyzed. Functional status was measured as activities of daily living (ADL) and instrumental ADL (IADL). The presence of comorbidity was assessed with a checklist of 33 items; items 29 and 30 of the European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-C30 (EORTC QLQ-C30) were used to estimate QoL. ADL was dichotomized as none versus one or more dependency. For IADL and QoL, three categories were defined using first and third quartiles as cut points. Comorbidity was summarized using the Charlson scale. Analysis was performed by Cox model, and stratified by treatment arm., Results: Better values of baseline QoL (P = .0003) and IADL (P = .04) were significantly associated with better prognosis, whereas ADL (P = .44) and Charlson score (P = .66) had no prognostic value. Performance status 2 (P = .006) and a higher number of metastatic sites (P = .02) also predicted shorter overall survival., Conclusions: Pretreatment global QoL and IADL scores, but not ADL and comorbidity, have significant prognostic value for survival of elderly patients with advanced non-small-cell lung cancer who were treated with chemotherapy. Using these scores in clinical practice might improve prognostic prediction for treatment planning.

Docetaxel (75 mg m(-2) 3-weekly) is standard second-line treatment in advanced non-small-cell lung cancer (NSCLC) with significant toxicity. To verify whether a weekly schedule (33.3 mg m(-2) for 6 weeks) improved quality of life (QoL), a phase III study was performed with 220 advanced NSCLC patients, < or =75 years, ECOG PS < or =2. QoL was assessed by EORTC questionnaires and the Daily Diary Card (DDC). No difference was found in global QoL scores at 3 weeks. Pain, cough and hair loss significantly favoured the weekly schedule, while diarrhoea was worse. DDC analysis showed that loss of appetite and overall condition were significantly worse in the 3-week arm in the first week, while nausea and loss of appetite were more severe in the weekly arm in the third week. Response rate and survival were similar, hazard ratio of death in the weekly arm being 1.04 (95% CI 0.77-1.39). A 3-weekly docetaxel was more toxic for leukopenia, neutropenia, febrile neutropenia and hair loss; any grade 3-4 haematologic toxicity was significantly more frequent in the standard arm (25 vs 6%). The weekly schedule could be preferred for patients candidate to receive docetaxel as second-line treatment for advanced NSCLC, because of some QoL advantages, lower toxicity and no evidence of strikingly different effect on survival.

The present study describes supportive care (SC) in patients with advanced non-small-cell lung cancer (NSCLC), evaluating whether it is affected by concomitant chemotherapy, patient's performance status (PS) and age. Data of patients enrolled in three randomised trials of first-line chemotherapy, conducted between 1996 and 2001, were pooled. The analysis was limited to the first three cycles of treatment. Supportive care data were available for 1185 out of 1312 (90%) enrolled patients. Gastrointestinal drugs (45.7%), corticosteroids (33.4%) and analgesics (23.8%) were the most frequently observed categories. The mean number of drugs per patient was 2.43; 538 patients (45.4%) assumed three or more supportive drugs. Vinorelbine does not produce substantial variations in the SC pattern, while cisplatin-based treatment requires an overall higher number of supportive drugs, with higher use of antiemetics (41 vs 27%) and antianaemics (10 vs 4%). Patients with worse PS are more exposed to corticosteroids (42 vs 30%). Elderly patients require drugs against concomitant diseases significantly more than adults (20 vs 7%) and are less frequently exposed to antiemetics (12 vs 27%). In conclusion, polypharmacotherapy is a relevant issue in patients with advanced NSCLC. Chemotherapy does not remarkably affect the pattern of SC, except for some drugs against side effects. Elderly patients assume more drugs for concomitant diseases and receive less antiemetics than adults.
